To all whom it may concern: therein by means of an open washer Z, which Be it known that I, J AOOB EWART BLACK- has a bearing against the ends of the sleeve 55 MORE, a citizen of the United States, residing d and the side walls of the grooves b, thereby at Pittsburg, in the county of Allegheny and preventing any movement of the axle A in 5 State of Pennsylvania, have invented certain the direction of its length.

new and useful Improvements in Car-Axles5 In constructing an axle A such as deand I do hereby declare the following to be a scribed the bushings c are first put in place 6o full, clear, and exact description of the invenin the sleeve cl and finished, the grooves b tion, such as will enable others skilled in the formed in the axle A, and the sleeves d and .1o art to which it pertains to make and use the bushing c slipped over the axle A. The same, reference being had to the accompanywashers Z are now tted into the grooves b, ing drawings, which form a partot' this speciwhich locks the sleeves d in position. The 65 fication. center piece g is loosely secured in place on My invention relates to an improvement in the tianged end f of one of the sleeves CZ by i 5 car-axles; and it consists in a divided axle passing the bolts h through the tia-nge f and coupled together at the center by means ot center piece g. The other sleeve CZ is now two sleeves, plain or ribbed, vsurrounding placed into position and the several part-s 7o the said axle and attached to a center piece rigidly attached together by means o t the by bolts in a manner that will permit the one bolts h. 2o wheel to revolve independent of the other, It will be seen that by means of this contogether with certain other details of construction of an axle the wheels n1, may restruction and combination of parts, as will be v olve entirely independent of each other, 75
